The current revision of the SHAKTI policy, enriched with innovative features, is set to significantly enhance its scope and impact across the power sector.

 In a meeting chaired by the PM Narendra Modi held recently Cabinet Committee on Economic Affairs (CCEA) approved the Revised SHAKTI (Scheme for Harnessing and Allocating Koyala Transparently in India) Policy for Coal Allocation to Power Sector. The Revised SHAKTI Policy adds to the series of coal sector reforms being undertaken by the Government.      

With the introduction of SHAKTI Policy in 2017, there was a paradigm shift of coal allocation mechanism from a nomination-based regime to a more transparent way of allocation of coal linkages through auction / tariff-based bidding. Now, the multiple paras of the SHAKTI Policy, for coal linkage, have been mapped to only two Windows in the Revised SHAKTI Policy, aligning with the spirit of ease of doing business, encouraging competition, efficiency, better use of capacity, seamless pit head thermal capacity addition and affordable power to the country.

The current revision of the SHAKTI policy, enriched with innovative features, is set to significantly enhance its scope and impact across the power sector. This update aims to provide greater flexibility in coal allocation, broaden the eligibility criteria to include more stakeholders, and improve overall accessibility to coal resources. Together, these changes are expected to strengthen the power sector’s operational efficiency and reliability.

The new policy will ensure coal linkage to all power producers leading to generation of more power, cheaper tariffs and an overall positive impact on the economy, thereby leading to increased employment generation potential. The reliable and affordable power supply to various sectors would catalyse economic activities and support the Atmanirbhar Bharat Initiative. The increased availability of domestic coal, in a simplified manner would also facilitate the revival of remaining stressed power assets. The linkage coal can now be used for generating power from Un-requisitioned Surplus (URS) capacity, for sale in power markets, which will not only deepen power markets by increasing availability of power in power exchanges but will also ensure optimum utilisation of generating stations.

Further, the new linkages offered to the power sector would increase the coal availability for the power sector and increase the mining activities in the coal bearing regions resulting in generation of higher revenue to the State Governments which can be utilised for development of these regions and local population in general. The policy would encourage pit head thermal capacity addition and facilitate imported coal substitution in the Imported Coal Based (ICB) plants that can secure domestic coal thereby reducing their import coal dependency. 

 The Revised SHAKTI Policy introduces two key windows for granting fresh coal linkages to Thermal Power Plants (TPPs) in the Central Sector, State Sector and Independent Power Producers (IPPs). Under Window-I, coal is allocated at the notified price. The existing mechanism for granting coal linkages to Central Sector TPPs, including Joint Ventures (JVs) and their subsidiaries, will continue. Additionally, coal linkages will be earmarked to States or to an agency authorised by a group of States based on recommendations from the Ministry of Power. These earmarked linkages can be used by State Gencos or IPPs identified through competitive bidding (TBCB) or existing IPPs with a PPA under Section 62 of the Electricity Act, 2003, including for setting up new or expansion units with PPAs under Section 62. 

Window-II allows all domestic coal-based power producers, including those using imported coal if required, to obtain coal through an auction by paying a premium over the notified price. This window supports flexibility in electricity sales and offers coal for periods ranging from up to 12 months to as long as 25 years. The revised policy aims to maximise the use of domestic coal, ensure smooth capacity addition in the thermal sector, reduce reliance on imported coal and strengthen the country’s energy independence in line with the government’s objective of ensuring Energy Security for All.

The Minister lauded the progress made by Goa in implementing infrastructure upgrades under the Revamped Distribution Sector Scheme (RDSS) to curb losses.

Power Minister Manohar Lal Khattar called on the Goa government to consider the possibility of establishing a nuclear power facility to boost local power generation and ensure long-term energy security and sustainability.

He emphasised the importance of exploring all possible avenues for local power generation to enhance self-reliance and reduce dependency.

Commending the Goa Electricity Department for its effective efforts in achieving universal electrification and maintaining consistent power availability, Khattar noted, “Goa has shown exemplary performance by reducing AT\&C (Aggregate Technical and Commercial) losses to 9.32 percent, significantly below the national average. This is a testament to the state’s sustained efforts in improving the efficiency of its power distribution system.”

The Minister lauded the progress made by Goa in implementing infrastructure upgrades under the Revamped Distribution Sector Scheme (RDSS) to curb losses. However, he stressed the need to expedite the rollout of smart meters, calling it a transformative step for consumer engagement with power distribution companies (DISCOMs).

“Now that the contracts have been awarded, I am confident the implementation will gain momentum. Prioritising saturation of smart meters in government offices, colonies, commercial and industrial units and high-load consumers will help ensure digitisation and improved service delivery,” Khattar added.

Highlighting the role of renewable energy in enhancing operational efficiency and reducing power costs, the Minister urged Goa to further integrate clean energy sources into the grid. He also acknowledged the state’s citizen-friendly initiatives in simplifying rooftop solar installations and new electricity connections.

The meeting concluded with an assurance from the Ministry of Power to provide full support to Goa in achieving its energy goals and strengthening its power infrastructure.

For utility-scale and grid-scale power projects, crystalline silicon (c-Si) modules must maintain a minimum efficiency of 20%, while cadmium telluride (CdTe) thin-film modules are required to meet a threshold of 19%. Similarly, for rooftop solar systems and solar-powered pumps, the minimum efficiency standards remain at 19.5% for c-Si modules and 18.5% for CdTe modules.

The Ministry of New and Renewable Energy (MNRE) has updated the minimum efficiency requirements for solar modules listed under the Approved List of Models and Manufacturers (ALMM). These revisions specifically apply to off-grid solar power projects and applications such as solar lamps, streetlights, fans, and similar systems where each solar module has a capacity of less than 200 Wp. Notably, solar-powered agricultural pumps and rooftop systems are excluded from these changes. Under the revised norms, the minimum efficiency requirement for crystalline silicon (c-Si) modules has been reduced from 19 percent to 18 percent  . Meanwhile, the efficiency standard for cadmium telluride (CdTe) thin-film modules remains unchanged at 18 percent. 

To accommodate these off-grid systems, MNRE has created a separate list within the ALMM framework, titled ALMM List-I (DRE), which will operate independently from the main ALMM List-I. Additionally, MNRE has introduced a new fourth category called “Any other application.” This includes solar projects that do not fall under utility/grid-scale, rooftop, solar pump, or off-grid classifications. For this category, the minimum efficiency requirements are set at 19 percent for c-Si modules and 18 percent   for CdTe thin-film modules. 

The minimum efficiency requirements remain unchanged for solar modules across various applications. For utility-scale and grid-scale power projects, crystalline silicon (c-Si) modules must maintain a minimum efficiency of 20 percent, while cadmium telluride (CdTe) thin-film modules are required to meet a threshold of 19 percent  . Similarly, for rooftop solar systems and solar-powered pumps, the minimum efficiency standards remain at 19.5 percent for c-Si modules and 18.5 percent for CdTe modules.

According to the National Crime Records Bureau, around one lakh people lost their lives because of electrocution in the last decade alone.

Electrocution, electrical fire and lightning kill 15,000 a year. Also 75000 (approx.) suffer because of these deaths, there is loss of property and assets, dreams of many people associated with deceased shatter. Around 1 lakh people died due to electrocution in the last decade, as per NCRB data.

NCRB data of deaths due to lighting electrocution and short circuit fire 2020-2022

According to the National Crime Records Bureau, around one lakh people lost their lives because of electrocution in the last decade alone. The annual average of fatalities rose to 12,500 per year or 30 fatalities every day. 

Causes of electrocution and electrical fire hazard 

Electrocution and electrical fires in electrical installations can result from various issues such as over currents caused by overloads or short circuits, presence of harmonics, and earth faults. Electric arcs in cables, loose connections and failure or incorrect selection of protection devices also pose significant risks. Additional causes include improper cable selection, mismatched lighting components, misuse of extension cords for heavy loads, and outdated or damaged equipment. Over voltages, inadequate earthing design, and lack of proper testing or verification further contribute to these hazards.

Role of adequate earthing/grounding

Grounding/earthing means making a connection to the general mass of earth. The use of grounding is so widespread in an electric system that at practically every point in the system from the generators to the consumers’ equipment, earth connections are made.

There are two types grounding:

1. Neutral grounding
2. General (equipment) grounding

Equipment and neutral earthing

The objectives of general grounding system

The general grounding system serves multiple critical objectives within a power system. It provides a low-resistance return path for fault currents, ensuring the safety of personnel and protection of equipment. By minimising ground potential rise (GPR) during faults, it prevents hazardous voltage differences with respect to remote ground. It also offers a safe discharge path for power system transients like lightning and over voltages. Additionally, the system ensures uniform potential bonding of conductive objects within a substation, reducing the risk of dangerous potential differences. It further prevents electrostatic charge buildup and allows sufficient fault current flow for proper operation of protection systems.

Unearth system and shock hazard

The main objective of grounding electrical systems is to provide a suitably low resistance path for the discharge of fault current which ultimately provides safety to working personnel and costly installed equipment by providing sufficient current to safety devices. 

Electrocution due to high-tension wires

Inadequate clearance: Temporary structures erected for public processions often lack proper planning and supervision, resulting in insufficient clearance between the structures and overhead high-tension wires. Failure to maintain adequate distance increases the risk of accidental contact, especially when structures sway due to wind or crowd movement. 

Ignorance and negligence: Organisers and participants may lack awareness about the dangers posed by high-tension wires or fail to recognise the potential hazards associated with erecting structures near them. Ignorance coupled with negligence in adhering to safety guidelines exacerbates the risk of electrocution incidents.

Lack of coordination: Coordination between event organisers, local authorities, and power distribution companies is often inadequate, leading to haphazard planning and implementation of safety measures. Failure to coordinate activities such as route planning, structure placement, and crowd management increases the likelihood of accidents involving high-tension wires.

Encroachment and unauthorised construction: Encroachment on public spaces and unauthorised construction near high-tension wire corridors is a common phenomenon in many Indian cities and towns. Informal settlements, temporary shelters, and makeshift structures often encroach upon the safety buffer zones around high-tension wires, heightening the risk of electrocution during public processions.

Electrical safety at industrial location, generating station and substations 

Industries, generating station and substations are critical components of electrical networks, but they also pose significant risks if safety measures are not strictly enforced. 

Causes of electrocution and fire in substations include:

High voltage exposure: Industries and substations contain high-voltage equipment that poses a severe risk of electrocution to untrained personnel or trespassers who come into contact with live components.

Equipment failure: Malfunctions or breakdowns of transformers, circuit breakers, and other substation equipment can result in electrical arcs, sparks, and fires.

Lack of proper enclosure: Unprotected or poorly enclosed panels or substations may expose electrical components to environmental factors such as moisture, debris, and wildlife, increasing the risk of failures and fires.

Inadequate security measures: Substations that lack sufficient security measures are vulnerable to unauthorised access, which can lead to tampering, theft, or vandalism that compromises safety.

Insufficient training: Workers at factories or substations must receive comprehensive training on electrical safety protocols and emergency procedures to mitigate risks effectively.

Golden rules to ensure safety

To ensure safety at industrial locations, substations or generating stations, follow these seven golden rules. Begin by thoroughly evaluating the task and conducting an on-site Hazard Identification and Risk Assessment (HIRA). Clearly identify the work location and the specific equipment involved. Apply for a permit to work and review the job details with the team. Disconnect electrical sources and secure them against reconnection using Lockout-Tagout (LOTO) procedures. Always verify the absence of voltage before starting work. Ensure proper earthing of the equipment being serviced. Finally, protect adjacent live parts and exercise extreme caution when working near bare conductors.

Conclusion

Regular maintenance and condition monitoring of electrical equipment are essential to prevent hazards. Routine inspections by qualified electricians ensure early detection of faults. Proper wiring, adherence to safety standards, and the use of overload protection devices like circuit breakers are crucial. Fire safety measures, including smoke alarms and extinguishers, must be in place. Keep electrical setups ventilated and clear of obstructions. Promote awareness about safe practices, especially during rain, waterlogging or public events. Emergency preparedness and lightning protection are vital. By taking these steps, we can reduce risks and ensure safety.

With a comprehensive portfolio of high-efficiency solar panels, sustainable energy solutions and a growing distribution network, PEWIN has been an active contributor to solar journey in India.

Panasonic Electric Works India, Panasonic Life Solutions India reaffirmed its strong and continued commitment to India’s growing solar energy sector. This announcement comes in the backdrop of Panasonic North America’s decision to discontinue its solar and battery storage business line.

The company clarified that the North American business restructuring will have no impact on its India solar operations. The company remains fully committed to the Indian market, where it continues to see tremendous potential for solar energy as a critical enabler of the country’s clean energy transition.

With a comprehensive portfolio of high-efficiency solar panels, sustainable energy solutions and a growing distribution network, PEWIN has been an active contributor to solar journey in India. The company plans to further scale its operations, cater to both residential and commercial demand and collaborate with developers, installers and government agencies to enhance access to reliable and clean energy solutions.

The company also assured its stakeholders that it remains committed to quality, customer service and innovation in the solar category. All existing commitments, warranties and after-sales support for Panasonic solar products in India continue as usual.

“India remains a strategic market for Panasonic’s solar business and we are fully aligned with the country’s renewable energy ambitions,” said Sanjay KVS, Business Unit Head, PEWIN, PLSIND. “We will continue to invest in strengthening our solar product offerings, deepen our partner ecosystem and support government and private sector initiatives aimed at accelerating solar adoption across the country,” he added.

“As the world moves towards decarbonisation, India is poised to play a leading role. PEWIN, Panasonic Life Solutions India will continue to be a reliable partner in this transition by providing technologically advanced, sustainable, and future-ready solar solutions,” Sanjay added.

Electricity demand in India is surging. There is a massive growth in the renewable energy sector. At the heart of this evolution lies the need for a robust, future-ready transmission and distribution (T&D) infrastructure. Bajel Projects Limited, a key EPC player, contributes significantly to this national mission. Formerly a part of Bajaj Electricals until 2023, Bajel Projects has a legacy of over two decades and has been a pioneer in manufacturing lattice structures and monopoles. Today, the company is crucial in executing transmission lines and substation projects across India and abroad.

The Indian power sector has witnessed remarkable growth in supply. In FY24, the overall supply stood at approximately 435 GW, rising to 470 GW in FY25. This surge is largely attributed to extensive solar capacity additions, a trend to accelerate in the coming years. By FY32, India is expected to have a generation capacity of around 1000 GW, nearly double the current levels. This expansion includes a substantial increase in solar power, which currently forms 19 per cent of the energy mix and is projected to rise to 39 per cent by FY32. Concurrently, peak demand—now around 250 GW—is projected to touch 458 GW, factoring in the upcoming load from emerging sectors like green hydrogen and green ammonia.

The country’s T&D infrastructure needs a proportional upgrade to support this exponential growth. According to the Central Electricity Authority (CEA), the government will need to add nearly 42 per cent more circuit kilometres over the next decade than all additions made. On the substation front, capacity is expected to leap from 1 million MVA to approximately 2.3 million MVA by FY32. This expansion will be driven equally by interstate and intrastate projects. While these projections are ambitious, many experts believe they are still conservative in light of India’s Viksit Bharat 2047 vision, which anticipates a peak demand of 700 GW. Therefore, planning must extend beyond the next decade to ensure that infrastructure remains viable for 20–25 years.

Substation capacity, a critical cog in the T&D wheel, saw substantial additions in the past year alone. India added around 86,000 MVA in substation capacity—a 22 percent increase from the previous year. States led the charge, followed by central entities like PGCIL and private players. PGCIL alone operated 276 substations in the previous fiscal year, of which 216 were Air-Insulated Substations (AIS) and 60 were Gas-Insulated Substations (GIS). Given the increasing space constraints and the need for reliability, GIS substations are now gaining prominence. GIS substations offer several advantages over traditional AIS. They require 60–75 percent less land, making them ideal for densely populated urban areas and industrial zones. They also perform better in harsh environmental conditions, such as flood-prone or high-wind regions, requiring lower maintenance and delivering higher reliability. Though they come with a higher initial cost, their overall cost of ownership—factoring in savings on land, manpower, and maintenance—is significantly lower. This makes GIS substations a more sustainable and efficient choice.

Several megatrends are pushing the shift toward GIS and smart substations. First, India’s data centre capacity is set to rise from 1 GW today to 17 GW by 2030—a 17-fold increase. These facilities, which are energy-intensive and space-constrained, are ideally suited for GIS substations. Second, sustainability imperatives are prompting a move away from SF6-based equipment and toward more energy-efficient and environmentally friendly alternatives. Lastly, integrating smart grids necessitates substations that are compact and reliable, digitally connected, and remotely operable. Smart substations are integral to building an intelligent and agile power network. India’s traditional grid systems were not designed with significant redundancy, leading to frequent outages. Introducing Loop in Loop Out (LILO) systems helped add redundancy, but the real game-changer is smart substations. These substations are equipped with SCADA and substation automation systems, allowing for remote monitoring and control. Upgrading older substations to smart configurations and ensuring interoperability through standardised communication protocols like IEC 61850 are essential next steps.

BSES Rajdhani Power Limited (BRPL), a key player in Delhi’s electricity distribution landscape, serves a significant portion of the capital city through its two companies—BSES Rajdhani and BSES Yamuna. Together, it caters to nearly two-thirds of the population, covering densely packed zones in South, West, Central, and East Delhi. With approximately five million customers and an astonishing circuit density of over 4,500 customers per square kilometre, BRPL is navigating unique challenges in scaling up its power infrastructure.

As Delhi continues to grow at an annual electricity demand rate of 5–6 per cent, expanding network capacity by 6–8 per cent every year becomes imperative. However, acquiring new land for substations and infrastructure is a persistent hurdle in a city where space is limited and increasingly expensive. Most available land falls under state control, which means every expansion requires inter-agency coordination and approvals, further complicating the process.

BRPL has focused on optimising existing assets and embracing innovative space-saving technologies to tackle these constraints. One major shift has been the conversion of traditional Air-Insulated Substations (AIS) to more compact Gas-Insulated Substations (GIS). This transformation allows BRPL to boost substation capacity without expanding its physical footprint. With recent Central Electricity Authority (CEA) guidelines permitting substation capacities up to 160 MVA at the 66/11 kV level, BRPL has achieved this threshold in select substations, significantly increasing capacity within constrained urban settings.

One GIS substation with a capacity of 63 MVA was commissioned in just 1,140 square meters, whereas regulations generally recommend that it be around 1,500 square meters. Another innovative solution includes packaged or E-house substations—containerised grid systems where switchgear is installed within compact units and power transformers are placed outside. These systems can be set up in as little as 600 square meters.

To further reduce space usage, BRPL has developed elevated and G+1 substations. The elevated substations built on single or double poles place distribution transformers on the top and switchgear below, reducing required space by up to 70–80 percent. The G+1 substations go further, housing two 1 MVA transformers on the upper level and RMUs and air circuit breakers on the ground floor. Remarkably, a G+1 substation requires only 13.7 square meters compared to 79 square meters for traditional layouts, an 85 percent space saving.

BRPL has also experimented with double-decker configurations in substations and low-tension (LT) switchgear systems. For instance, in the LT segment the double-decker air circuit breaker system places one breaker above the other, reducing the equipment footprint without compromising functionality.

Cable technology has also evolved. Previously, separate high-density polyethylene (HDPE) ducts and power cables were laid independently, causing inefficiencies and potential quality issues. Now, BRPL has transitioned to co-extruded cables, where the HDPE sheathing is fused with the cable itself. This simplifies installation, reduces costs, and ensures better reliability. Around 500–600 km of such cables are now laid annually.

In addition to physical infrastructure upgrades, BRPL is embracing energy storage technologies to manage the national capital’s unique peak demand curve. The city experiences two distinct peaks—late afternoon and late evening—which only constitute a small portion of the year. BRPL began deploying modular battery storage systems at the distribution transformer level to address these short-duration spikes without excessive capital investment. After successful pilots since 2021, these systems are now being rolled out citywide.

On a larger scale, a 40 MWh grid-connected battery storage system capable of supplying 20 MW for two hours has been installed. This installation alleviates stress not just on the distribution grid but also on the upstream transmission network, providing critical flexibility and reducing the need for costly infrastructure upgrades.

From elevated substations to battery-backed transformers, BRPL’s adaptive and forward-looking approach exemplifies how utilities can ensure a reliable, efficient, and sustainable power supply in dense urban environments. With a focus on modular, compact, and technologically advanced solutions, BSES Rajdhani Power Limited (BRPL) continues to power the capital, meeting the demands of the present while preparing for the future.

Over the last eleven years, Telangana has witnessed a phenomenal transformation in its power transmission infrastructure, making it one of India’s most reliable and efficient networks. From a modest beginning, the state has built over 5,000 circuit kilometres of transmission lines and dramatically expanded its substation network. The total contracted generation capacity in the state now stands at approximately 20,520 MW. Telangana boasts a robust transmission infrastructure that includes 29 substations of 400 kV, 105 substations of 220 kV, and 254 substations of 132/33 kV, creating a comprehensive grid that ensures connectivity across urban and rural areas.

A notable highlight is the expansion of 400 kV transmission lines, which increased from just 600 km to over 7,070 km, enabling the state to meet peak power demands efficiently—recently reaching a record 17,162 MW. Advanced technologies like gas-insulated substations (GIS) have been widely adopted. The state has established around 15 GIS substations, including a four-level voltage GIS substation in Hyderabad that integrates 400 kV, 220 kV, 132 kV, and 33 kV levels within a compact 5-acre plot in the city’s heart. For the past eight years, this strategic investment has ensured an uninterrupted 24-hour power supply to all consumers, including over 30 lakh agricultural customers.

Regarding renewable energy integration, Telangana has successfully connected around 6,000 MW of solar power to the grid without additional transmission infrastructure, as these are largely load-side connections. An additional 2,469 MW of solar capacity is under construction. The state has formed a triple-layered transmission ring around Hyderabad, ensuring reliable power evacuation from generation sources to end users. These include an innermost 400 kV ring within the city, a mid-level ring connecting surrounding substations and an outer ring about 100 km from Hyderabad that connects interstate networks and major generation facilities. Telangana is also home to advanced substations, such as the underground 400 kV GIS substation, which was built 100 meters below ground.

Telangana has kept its network availability at an impressive 99.98 per cent over the last seven years, while transmission losses have been significantly reduced from 4.3 per cent at the time of state formation to just 2.16 per cent recently. This reduction has been achieved by strategic planning and efficient implementation of technologies like High-Temperature Low Sag (HTLS) conductors. In Hyderabad alone, HTLS retrofitting three transmission lines saved the state over ₹1,100 crore compared to installing new underground cable systems. Approximately 20 such lines have been upgraded, with another 30 lines planned for conversion over the next five years.

Innovative space-saving solutions have also been deployed, such as using monopole towers for 400 kV double circuit lines in core urban areas, GIS substations where land is limited, and bus model systems to enhance substation capacity without new land acquisition. The transmission network is entirely geo-mapped, with every tower and substation integrated into a geographic information system, enabling precise planning and asset management. Outdoor GIS substations, like the one at Manikonda, have also been introduced with two 80 MVA transformers supplying 33 kV feeders.

The state is also leading in digitisation and automation, with many substations now operating remotely. One example includes 132 kV substations being monitored from centralised 220 kV stations, reducing manpower while increasing efficiency. The future roadmap includes the addition of 12 new 400 kV substations, 25 substations at 220 kV and 47 at 132 kV, alongside widespread transformer capacity enhancements based on projected load growth.

To strengthen human resource capabilities, a comprehensive handbook containing over 1,400 frequently asked questions is being compiled and distributed. It will become a widely respected reference in the electrical utility sector. Recognised for its achievements, the state’s transmission sector has won several national awards and is now considered a benchmark for others.
